Knowledge on the capability of zooplankton to adapt to the rapidly changing environmental conditions in the Arctic is crucial to predict future ecosystem processes. The key species on the Arctic shelf, the calanoid copepod Calanus glacialis, grows and accumulates lipid reserves in spring and summer in surface waters. The winter is spent in dormancy...

We investigated the possibility of utilizing both oleaginous yeast species accumulating large amounts of lipids (Yarrowia lipolytica, Rhodotorula glutinis, Trichosporon cutaneum, Candida sp.) and traditional biotechnological non-oleaginous ones characterized by high biomass yield (Kluyveromyces polysporus, Torulaspora delbrueckii, Saccharomyces cer...

The lipid composition and content were analyzed in lettuce Lactica sativa L. (variety Stone head) leaves grown in a weak horizontal permanent magnetic field (PMF) produced by Helmholtz coils of 400 A/m strength under controlled conditions of illumination and temperature in phytothrone. Control plants were grown under the same conditions in a geomag...

Chlorpyrifos (CPF), an organophosphate widely applied in agriculture and aquaculture, induces oxidative stress due to free-radical generation and changes in the antioxidant defense system. The present study investigated the short-term effect of CPF exposure on the oxidative and antioxidant systems and their recovery responses in metabolically activ...

Coral bleaching events are associated with abnormal increases in temperature, such as those produced during El Niño. Recently, a breakdown in the coral–dinoflagellate (genus Symbiodinium) endosymbiosis has been documented in corals exposed to anomalously cold-water temperatures associated with La Niña events. Given the ecological significance of su...

Orthorhombic (spherical; ~10 nm) and monoclinic (cylindrical; ~50 nm) sulfur nanoparticles (SNPs) were synthesized and examined for their effects on the total lipid content and desaturase enzymes of Aspergillus niger. Synthesized SNPs were characterized for size with transmission electron microscopy, elemental composition with energy dispersive X-r...

We studied the lipid dynamics (lipid contents, classes and fatty acids) during oogenesis and early embryogenesis of 7 viviparous and 3 oviparous deepwater chondrichthyans. Mature pre-ovulated ovarian follicles of all species were high in lipid content, indicative of large energetic expenditure and high maternal investment. Larger lipid reserves wer...

Cape hakes, Merluccius paradoxus and M. capensis, are important gadoid fish that are commercially harvested in the Benguela Current system off Namibia and South Africa. The aim of this study was to elucidate the nutritional condition and feeding preferences of their larvae. Hake eggs and larvae were sampled in austral spring of two consecutive year...

Carnivorous zooplankton is a key element to the energy transfer through the arctic food web, linking lipid rich herbivores to the top predators. We investigated the growth and lipid dynamic of the Arctic pelagic amphipod Themisto libellula in Kongsfjorden (Svalbard, 79°N) from May to October 2007. Additional samplings were performed in spring and s...
